PHILADELPHIA - The iconic Liberty Bell's latter-day twin, bestowed to the city as a bicentennial gift from Britain, was removed from its hulking tower at a defunct visitors centre on Thursday and placed in storage.

The Bicentennial Bell was cast in the same British foundry as the original, a symbol of the U.S. as familiar as the Stars and Stripes, and had been presented to Philadelphia by Queen Elizabeth II to commemorate America's 200th birthday.

The National Park Service on Thursday removed the six-ton bell from its 130-foot-tall brick tower, an imposing square column that may have seemed like a good design in the 1970s but effectively hid the bell from view. The tower and its equally inhospitable-looking neighbour, a box-like brick building that formerly was a visitors centre, were constructed for the bicentennial and are being demolished for a new Revolutionary War museum.

The Bicentennial Bell was cast in 1976 at London's Whitechapel Foundry, where the Liberty Bell was also made in 1751. An inscription reads: "For the People of the United States of America from the People of Britain / 4 July 1976 / LET FREEDOM RING."

It was presented by Queen Elizabeth and Prince Philip, who disembarked from the royal yacht Britannia on July 6 to abundant fanfare at Penn's Landing on the Delaware River. Their arrival marked the first time a British monarch had visited Philadelphia, birthplace of the Declaration of Independence that severed the Colonies' ties from the crown.

The queen, a direct descendant of the patriots' nemesis King George III, indicated there were no hard feelings. She told a crowd of 20,000 at the Bicentennial Bell's dedication ceremony that, 200 years earlier, the founding fathers taught her country "to respect the right of others to govern themselves in their own way."

The bell will remain mothballed until a new home is found. A spokeswoman for The Museum of the American Revolution, slated to open on the site in late 2015, did not immediately return a message seeking comment.

The Bicentennial Bell is missing its predecessor's famous crack but it also doesn't work. It did ring twice a day for about 25 years, until an automated mechanism that worked the clapper broke. The Park Service said it has lacked funding to repair it.
